Comprehensive geriatric assessment for older patients with cancer

Geriatric assessment in oncology practice

There is no standard tool for assessing the "functional age" of an older adult with cancer, although it is widely recognized that chronological age does not capture the heterogeneous physiological and functional status of older adults. Integrating a "geriatric assessment" into oncology research and clinical practice would help fill this void. Geriatric assessment covers factors that predict morbidity and mortality in older adults, including functional status, comorbidity, cognition, psychological state, nutritional status, and social support. This assessment provides a broader overall understanding of individual characteristics that affect life expectancy. In addition, this assessment identifies areas of vulnerability in older adults for which further evaluation or intervention is indicated. This article will address the utility of a geriatric assessment in oncology practice, review data that attest to the benefits of the assessment, and issue a call for further research into how this assessment can be integrated into oncology care. Doing so will help develop targeted interventions and optimize cancer outcomes in this rapidly growing population.

EORTC elderly task force position paper: approach to the older cancer patient

As a result of an increasing life expectancy, the incidence of cancer cases diagnosed in the older population is rising. Indeed, cancer incidence is 11-fold higher in persons over the age of 65 than in younger ones. Despite this high incidence of cancer in older patients, solid data regarding the most appropriate approach and best treatment for older cancer patients are still lacking, mostly due to under-representation of these patients in prospective clinical trials. The clinical behaviour of common malignant diseases, e.g. breast, ovarian and lung cancers, lymphomas and acute leukaemias, may be different in older patients because of intrinsic variation of the neoplastic cells and the ability of the tumour host to support neoplastic growth. The decision to treat or not these patients should be based on patients' functional age rather than the chronological age. Assessment of patients' functional age includes the evaluation of health, functional status, nutrition, cognition and the psychosocial and economic context. The purpose of this paper is to focus on the influence of age on cancer presentation and cancer management in older cancer patients and to provide suggestions on clinical trial development and methodology in this population.

Prognostic factor and quality of life analysis in 160 patients aged > or =60 years with hematologic neoplasias treated with allogeneic hematopoietic cell transplantation

Toxicity-reduced conditioning is a curative treatment option for medically compromised or elderly patients ineligible for myeloablative hematopoietic cell transplantation (HCT). The aim of this study was to detect prognostic factors for overall survival (OS) and to evaluate quality of life (QOL) in a large homogeneous cohort of 160 consecutive patients aged > or =60 years treated with allogeneic HCT. We evaluated age, sex, performance status, comorbidities, pulmonary function, lactic dehydrogenase concentration, type of donor, disease status, CD34(+) cells transplanted, cytomegalovirus status, time from diagnosis to HCT, and the development of acute and chronic graft-versus-host disease (GVHD). All patients who survived for > or =6 months (n = 79) were asked to complete a QOL survey. All patients (median age, 64.7 years; range, 60.1-76 years) received pretransplantation conditioning with fludarabine, BCNU, and melphalan. With a median follow-up of 35 months, the 1-year OS was 62.4% and 3-year OS was 47.4%. Multivariate analysis revealed compromised performance status as the most significant negative prognostic parameter for OS (P < .003), whereas male donor (P = .008) and chronic GVHD (P = .024) were associated with better OS. The 89% of survivors who returned the QOL questionnaire rated their global QOL as good-to-excellent despite impaired functional capabilities and such symptoms as fatigue, dyspnea, and loss of appetite. The main prognostic factor was performance status, not age. Our data suggest that toxicity-reduced conditioning offers a chance for enhanced OS with an adequate QOL.

Management of head and neck cancer in elderly patients

Head and neck cancer (HNC) represents a heterogeneous group of tumours requiring multimodality approaches. It is debatable whether HNC treatment in geriatric patients should be different to that delivered for younger patients. Furthermore, the risk of death seems to be higher in HNC patients with higher co-morbidity status. Despite the fact that there is no significant difference in outcome in younger versus older patients, older HNC patients are more likely to receive nonstandard, less aggressive therapies than younger patients. Age alone should not be the basis for selecting treatment options in older HNC patients. A thorough pretreatment evaluation of co-morbidities should always be performed, and radical surgical options should not be excluded in older HNC patients treated with curative intent, as postoperative complications occur no more frequently in older patients than in younger patients. Locoregional control and disease-free survival in older patients treated with radiation therapy (either with curative intent or in the palliative setting) are comparable to the results seen in younger HNC patients, with the same acute toxicity profile. In patients receiving systemic therapies, special attention must be given to modification of chemotherapy dosages according to renal and hepatic function. Molecular-targeted therapies appear to be very useful in such patients because of their favourable tolerability. In conclusion, once all physiological and biological risk factors have been addressed, a large proportion of geriatric patients can and should be offered the same HNC treatment as is offered to younger patients.

Are gold standard depression measures appropriate for use in geriatric cancer patients? A systematic evaluation of self-report depression instruments used with geriatric, cancer, and geriatric cancer samples

PURPOSE

Geriatric issues in cancer are becoming prominent. Depression is a significant concern for both the elderly and patients with cancer, yet identifying depression in these patients is difficult and often leads to under-recognition. We conducted a systematic review to determine which depression instruments are appropriate for use in geriatric patients with cancer.

METHODS

We identified the most commonly used self-report depression instruments. We then used the criteria established in the US Food and Drug Administration Draft Guidance on Patient-Reported Outcome Measures to determine the extent of validation evidence of these measures in geriatric cancer populations. Finally, we determined which instruments captured depressive symptoms that are common among elderly patients with cancer.

RESULTS

Eight measures were selected as the most commonly used instruments. These were the Beck Depression Inventory-II, Brief Symptom Inventory-18, Center for Epidemiologic Studies-Depression Scale, Geriatric Depression Scale-15, Hospital Anxiety and Depression Scale, Patient Health Questionnaire-9, Profile of Mood States-Short Form, and Zung Self-Rating Depression Scale. Many have been validated for use with geriatric adults and patients with cancer; however, data addressing content validity and responder definition were lacking. To date, there is no validation information for geriatric patients with cancer. Furthermore, symptom profile analysis revealed that these measures do not identify many symptoms signaling depression in geriatric patients with cancer.

CONCLUSION

The validation evidence for use of common depression instruments in geriatric patients with cancer is lacking. This, and the possibility that these measures may not assess common depressive symptoms in geriatric patients with cancer, questions the adequacy of these scales in this population.

An evaluation of lower-body functional limitations among long-term survivors of 11 different types of cancers

BACKGROUND

The authors examined potential reasons (sociodemographics, psychologic distress, health behavior, chronic health conditions, access to medical care) for increased prevalence of lower-body functional limitations among long-term (> or =5 years) cancer survivors.

METHODS

The authors used National Health Interview Survey data from 2005 through 2007, and defined lower-body functional limitation as reporting difficulty/inability to perform at least 1 of 5 activities (walking approximately one-quarter of a mile; walking up and down 10 steps without rest; standing for 2 hours; stooping, crouching, or kneeling; and lifting 10 lbs). Increased prevalence of lower-body functional limitations was compared between long-term survivors of each of 11 cancer types reported by > or =50 respondents (n = 2143) and persons without cancer history (controls; n = 72,618).

RESULTS

Among cancer survivors, 57.0% had a lower-body functional limitation versus 26.6% of controls. The unadjusted prevalence of lower-body functional limitations varied by cancer type, ranging from 44.9% (lymphoma survivors) to 88.8% (lung cancer survivors). Long-term lung (odds ratio [OR], 7.91), uterine (OR, 2.41), thyroid (OR, 2.27), cervical (OR, 1.76), ovarian (OR, 1.75), and breast (OR, 1.35) cancer survivors had increased odds of reporting a lower-body functional limitation than controls after adjusting for sociodemographic factors (all P < .05). Differences in the prevalence of arthritis and lower-back pain and in access to medical care explained differences in lower-body functional limitation prevalence between controls and long-term breast, cervical, ovarian, and uterine cancer survivors. Long-term bladder, colorectal, lymphoma, melanoma, and prostate cancer survivors were equally likely to report a lower-body functional limitation as controls.

CONCLUSIONS

Treatment of arthritis and lower-back pain and increasing access to medical care might help reduce the risk of lower-body functional limitations and improve quality of life among specific long-term cancer survivors.

Older breast cancer survivors: geriatric assessment domains are associated with poor tolerance of treatment adverse effects and predict mortality over 7 years of follow-up

PURPOSE

To evaluate geriatric assessment (GA) domains in relation to clinically important outcomes in older breast cancer survivors.

METHODS

Six hundred sixty women diagnosed with primary breast cancer in four US geographic regions (Los Angeles, CA; Minnesota; North Carolina; and Rhode Island) were selected with disease stage I to IIIA, age >or= 65 years at date of diagnosis, and permission from attending physician to contact. Data were collected over 7 years of follow-up from consenting patients' medical records, telephone interviews, physician questionnaires, and the National Death Index. Outcomes included self-reported treatment tolerance and all-cause mortality. Four GA domains were described by six individual measures, as follows: sociodemographic by adequate finances; clinical by Charlson comorbidity index (CCI) and body mass index; function by number of physical function limitations; and psychosocial by the five-item Mental Health Index (MHI5) and Medical Outcomes Study Social Support Survey (MOS-SSS). Associations were evaluated using t tests, chi(2) tests, and regression analyses.

RESULTS

In multivariable regression including age and stage, three measures from two domains (clinical and psychosocial) were associated with poor treatment tolerance; these were CCI >or= 1 (odds ratio [OR] = 2.49; 95% CI, 1.18 to 5.25), MHI5 score less than 80 (OR = 2.36; 95% CI, 1.15 to 4.86), and MOS-SSS score less than 80 (OR = 3.32; 95% CI, 1.44 to 7.66). Four measures representing all four GA domains predicted mortality; these were inadequate finances (hazard ratio [HR] = 1.89; 95% CI, 1.24 to 2.88; CCI >or= 1 (HR = 1.38; 95% CI, 1.01 to 1.88), functional limitation (HR = 1.40; 95% CI, 1.01 to 1.93), and MHI5 score less than 80 (HR = 1.34; 95% CI, 1.01 to 1.85). In addition, the proportion of women with these outcomes incrementally increased as the number of GA deficits increased.

CONCLUSION

This study provides longitudinal evidence that GA domains are associated with poor treatment tolerance and predict mortality at 7 years of follow-up, independent of age and stage of disease.

Impact of comorbidities on clinical outcomes in non-small cell lung cancer patients who are elderly and/or have poor performance status

AIM

We evaluated the effect of comorbidities on clinical outcomes in patients with advanced non-small cell lung cancer (NSCLC) who have poor performance status (PS 2/3) and/or are elderly (≥70 years old). SUMMARIZED DESCRIPTION: The impact of age (<70 versus >70), PS, and comorbidity score - Cumulative Illness Rating Scale for Geriatrics (CIRS-G) on treatment response, toxicities, QOL and overall survival (OS) was analyzed using data from a completed phase II trial that randomly assigned patients with advanced NSCLC who had PS 2/3 and/or were aged ≥70 to receive gemcitabine (GEM), vinorelbine (VIN) or docetaxel (DOC).

RESULTS

Data from records of 134 patients accrued during the trial were available for analysis. Eighty-eight patients (66%) were aged ≥70 years. 59 patients (67%) had PS of ECOG 0-2 and 29 patients (33%) had ECOG 3. In those aged ≥70, 53 (60%) had at least one comorbidity rated CIRS-G category 3/4 while those aged <70, 12 (26%) had at least one CIRS-G 3/4 comorbidity. Age, PS, and comorbidity scores had no significant association with PFS and QOL scores changes, although PS had marginal influence on OS (0.05<p<0.10). There was significantly greater hematological toxicities and fatigue in patients who had comorbidities of a severe nature. The presence of comorbidity rated CIRS-G category 4 was significantly associated with lower dose intensity of drugs received with no overall impact on response nor survival. In the multivariate analysis, only older patients retained significance with favorable hazard ratio (HR) of 0.5 for overall survival.

CONCLUSIONS

Presence of comorbidities alone should not deter the oncologist from treating elderly cancer patients with cytotoxics. Patients with severe comorbidities may experience more toxicity and receive less cycles of chemotherapy and early medical intervention to control these comorbidities may mitigate risk of treatment using cytotoxics.

A comprehensive geriatric assessment is more effective than clinical judgment to identify elderly diffuse large cell lymphoma patients who benefit from aggressive therapy

BACKGROUND

The authors set out to analyze if a simple comprehensive geriatric assessment (CGA) could objectively identify elderly patients with diffuse large cell lymphoma (DLCL) who can be effectively treated with anthracycline-containing immunochemotherapy.

METHODS

CGA was performed in 84 consecutive patients with DLCL aged >65 years and diagnosed at a single institution. Treatment with curative versus palliative intent was chosen according to clinical judgment. Cyclophosphamide, hydroxydaunomycin, Oncovin (vincristine), and prednisone (CHOP) or CHOP-like regimens were given to 62 (74%) patients. The outcome of patients was analyzed according to both the treatment received and the results of CGA.

RESULTS

According to CGA, 42 (50%) patients were classified as "fit." They were younger (P < .0001) and had less frequent systemic symptoms (P = .03). These patients received curative treatment by clinical judgment. Their response rate (92.5% vs 48.8%; P < .0001) and median survival (not reached vs 8 months; P < .0001) were significantly better than those of 42 patients considered "unfit" by CGA. Among unfit patients, 20 had actually received curative and 22 palliative therapy. These subgroups did not differ in any geriatric or lymphoma-related characteristic. Their outcome was similar irrespectively of the type of treatment received (median survival, 8 vs 7 months; P = nonsignificant). Lymphoma rather than toxicity was the main cause of failure/death also among unfit patients treated aggressively.

CONCLUSIONS

CGA is an efficient method to identify elderly DLCL patients who can benefit from a curative approach with anthracycline-containing immunochemotherapy. Further study is needed to discern why unfit patients seem to have poor outcomes because of poor tolerance but also because of lymphoma refractoriness to intensive therapy.

Bladder cancer in the elderly

INTRODUCTION

Age is now widely accepted as the greatest single risk factor for developing bladder cancer, and bladder cancer is considered as primarily a disease of the elderly. Because of the close link between age and incidence of bladder cancer, it can be expected that this disease will become an enormous challenge with the growth of an aging population in the years ahead.

METHODS

Using MEDLINE, a search of the literature between January 1966 and July 2007 was performed to describe normative physiologic changes associated with aging, elucidate genetic and epigenetic alterations that associate aging with bladder cancer and its phenotypes; and to characterize how aging influences efficacies, risks, side effects, and potential complications of the treatments needed for the various stages of bladder cancer.

RESULTS

We discuss influence of aging on host physiology, genetic and epigenetic changes, environmental influences, and host factors in the development and treatment of bladder cancer. Treatments with intravesical bacille Calmette Guerin, radical cystectomy, and perioperative chemotherapy are less well tolerated and have poorer response in elderly patients compared with their younger counterparts. Elderly patients face both clinical and broader institutional barriers to appropriate treatment and may receive less aggressive treatment and sub-therapeutic dosing. However, when appropriately selected, elderly patients tolerate and respond well to cancer treatments.

CONCLUSIONS

The decision to undergo treatment for cancer is a tradeoff between loss of function and/or independence and extension of life, which is complicated by a host of concomitant issues such as comorbid medical conditions, functional declines and "frailty", family dynamics, and social and psychologic issues. Chronological age should not preclude definitive surgical therapy. It is imperative that healthcare practitioners and researchers from disparate disciplines collectively focus efforts towards gaining a better understanding of what the consequences of bladder cancer and its treatments are for older adults and how to appropriately meet the multifaceted medical and psychosocial needs of this growing population.

Nutritional assessment in geriatric cancer patients

INTRODUCTION

Geriatric patients are not defined by their age but by their general profile. Aging is characterized by loss of organ function together with a reduced capability for adapting to changes in the environment (loss of homeostatic mechanisms) leading to frailty. In the older patient with cancer, there can be problems of dietary intake next to the effects of aging per se. On top of this situation, the deleterious effects of the inflammatory processes induced by the tumor are superimposed. When these changes are translated into nutritional concepts, it is clear that, in the older cancer patient, there is a strong overlap of starvation, sarcopenia, and cachexia.

DISCUSSION

Nutritional assessment should be part of the routine preliminary evaluation of the older oncology patient. Difference should be made between assessment of risk and actual nutritional status, which should be assessed with specific malnutrition indices. Body weight assessment with specific attention to unintended weight loss is essential in this evaluation. One should recognize the fact that body mass index (BMI) should be interpreted with caution, but that a low value for BMI still heralds an increased malnutrition risk. This increased alertness for nutritional problems has a lot to offer in the willingness for early intervention. The nutritional assessment, however, must be framed in a larger comprehensive geriatric assessment addressing several functional domains.

Randomized phase II trial of weekly paclitaxel combined with carboplatin versus standard paclitaxel combined with carboplatin for elderly patients with advanced non-small-cell lung cancer

BACKGROUND

The optimal platinum doublet regimen in elderly patients with non-small-cell lung cancer (NSCLC) is still uncertain. We conducted a randomized phase II study to compare the efficacy and safety of weekly paclitaxel combined with carboplatin with those of the standard schedule.

PATIENTS AND METHODS

Elderly patients (age > or =70 years) with advanced NSCLC were randomly assigned to either the weekly arm {70 mg/m(2) paclitaxel on days 1, 8, and 15 and carboplatin [area under the curve (AUC) = 6] on day 1} or the standard arm [200 mg/m(2) paclitaxel and carboplatin (AUC = 6) on day 1]. The primary end point was the overall response rate (ORR).

RESULTS

Eighty-two patients were enrolled. The ORR and median progression-free survival were 55% and 6.0 months for the weekly arm and 53% and 5.6 months for the standard arm. Grade 3/4 neutropenia and peripheral neuropathy were observed in 41% and 0% of the patients in the weekly arm and in 88% and 25% in the standard arm, respectively.

CONCLUSIONS

This is the first randomized study that compares the platinum doublet designed specifically for the elderly. Regarding the safety, the weekly regimen was less toxic than the standard regimen and seems to be preferable for elderly patients with advanced NSCLC.

Clinical relevance of extra-hematologic comorbidity in the management of patients with myelodysplastic syndrome

Myelodysplastic syndromes occur mainly in older persons, and these patients are likely to have comorbidities that significantly worsen their survival. In this perspective article, Drs. Della Porta and Malcovati examine the relevance of comorbidities for clinical decision making in patients with myelodysplasti syndromes.

Oral cavity squamous cell carcinoma in 260 patients aged 80years or more

PURPOSE

We report the experience of two French cancer centers in the treatment of oral cavity squamous cell carcinoma (SCC) in patients aged 80 years.

MATERIALS AND METHODS

Two hundred and sixty patients aged 80 years with a primary oral cavity SCC were included in this retrospective analysis.

RESULTS

Sex ratio was near to 1. Tobacco or alcohol intoxication was the main risk factor for 66% of men and 16% of women and leukoplakia, lichen planus, or oral traumatism for 55% of women and 11% of men (p<0.0001). Two hundred patients received a loco-regional (LR) treatment with a curative intent (surgery and/or radiotherapy), 29 with a palliative intent and 31 did not receive a LR treatment. Curative treatments were initially planned to be adapted to age in 118 patients (59%). The median disease-specific survival (DSS) was 29 months. In multivariate analysis, the independent prognostic factors for DSS were stage (HR=0.42 [0.24-0.72]), age (HR=0.43 [0.24-0.75]) and performance status (HR=0.50 [0.27-0.95]). The median overall survival (OS) was 14 months. In multivariate analysis, the independent prognostic factors for OS were age (HR=0.52 [0.35-0.79]), stage (HR=0.56 [0.38-0.84]), tumor differentiation (HR=0.60 [0.33-0.93]) and performance status (HR=0.6 [0.37-0.97]). In patients treated with a curative intent, treatment adapted to age was not associated with a decreased overall survival or disease-specific survival as compared with the standard treatment. However, prophylactic lymph node treatment in stages I-II tumors decreased the rate of nodal recurrence from 38% to 6% (p=0.01).

CONCLUSION

This study emphasizes the need for prospective evaluation of standard and adapted schedules in elderly patients with oral cavity cancer.

Six independent domains are defined by geriatric assessment in elderly cancer patients

BACKGROUND

Geriatric assessment (GA) must be integrated into treatment concepts for elderly cancer patients. Aim of this study was to assess the coverage of a large battery of GA instruments by determining the number of independent domains measured.

METHODS

Thirteen different GA scores were applied in 78 elderly tumor patients (mean age 72.9 years). Data were analyzed by exploratory factor analysis and substantiated by non-parametric correlation analyses.

RESULTS

Factor analysis yielded a six-factor solution explaining 77.1% of the total variance. The six domains identified may be described as general functioning in everyday life, health-related quality of life, co-morbidities, social support, cognition, and nutritional status. This factor structure was reasonably well confirmed by correlation analyses. Notably, WHO Performance Status, Karnofsky Index, VES-13 and PPT generally revealed high correlations with functional capacities, but only low correlations with comorbidities, social support, cognitive functioning or nutritional status.

CONCLUSIONS

From the six domains described a basis for efficient application of GA instruments in elderly cancer patients is worked out. The classical instruments WHO and KI as well as the screening scores VES-13 and PPT, while capturing physical functioning well, fail to cover several other important GA domains.

Can we better manage Unfit older cancer patients?

The term Unfit refers to older cancer patients not amenable with standard treatment and needing therefore a modified or attenuated treatment or also not deserving an active therapeutic approach. To determine whether an old patient is Unfit a Multidimensional Geriatric Evaluation is needed, but to spare time, shortened tools of evaluation are now in a phase of development. Most of the available data on older cancer patients derive from clinical prospective studies carried out in a selected population, with the exclusion then of Unfit patients. The challenge of this special issue of CTR is that of providing a clinically useful information on the basis of the results of the available studies and expert opinion in the main tumor types.

Colon cancer in older adults

Colorectal cancer (CRC) is a common malignancy in the elderly. Randomized trials have demonstrated that adjuvant and palliative chemotherapy for CRC improves survival and quality of life. Unfortunately, there is a lack of evidence-based data about elderly patients to guide decisions regarding therapy. Clinical trials have generally excluded the vulnerable elderly population commonly seen in practice and included the robust elderly, who seem to benefit from chemotherapy as much as younger patients. The existing literature consists of pooled datasets from large studies and a few small dedicated trials on chemotherapy and its toxicity in elderly patients with CRC. We present illustrative data in this article and summarize our recommendations for managing the disease in elderly patients in a variety of clinical circumstances.

Frail old patients as a target population for cancer trials

The recent distinction between co-morbidity and multi-morbidity well stresses the difficulty of managing old patients with cancer whose complexity is not captured by a list of diagnoses or biological burden alone. The most adequate answer found by oncologists and geriatricians was to work together for better evaluating the physiological age and body reserve of the patient. The gold standard tool to assess old patient with cancer is named Comprehensive Geriatric Assessment. Its systematic application needs geriatric competences and time. In this context, a great number of cancer patients are considered as "frail" because they have reduced available physiological reserves. They might not withstand stress when challenged. Oncologists and geriatricians have imagined an innovative process to change the screening procedure of these patients, determine the prognosis, adapt the treatment strategy, to increase the patient's survival and his/her quality of life. The internet website "www.clinicaltrials.com" only lists 8 studies focused on frail elders with cancer. Six of them are focused on specific cancers or specific treatments, one was applied to all kind of cancers and the last was an opinion overview from oncologists and geriatricians. The selection criteria of frail patients are very diverse and probably include cancer patients who are not comparable. It is now time to try to identify new practical, reliable and accurate tools to facilitate the inclusion of the same kind of patients suffering from the same kind of cancer to be able to give more appropriate care and at the same time to constitute a valuable data base. Existing tools are reviewed and analyzed.

Review article: benefits and risks of chemotherapy in elderly patients with metastatic colorectal cancer

BACKGROUND

Although metastatic colorectal cancer (mCRC) is largely a disease of older individuals, our understanding of disease processes and their optimal treatment has been gained through trials with populations largely confined to younger individuals.

AIM

To identify through a review issues specific to geriatric patients with mCRC (physiological changes associated with aging, burden of coexisting illnesses, altered drug pharmacokinetics and functional impairment) and assess challenges to elderly patients posed by malignancy and exposure to cytotoxic medication.

METHODS

Our literature search for indexed articles published between 2000 and May 2008 employed terms including irinotecan, oxaliplatin, elderly, mCRC, targeted agents and biologicals.

RESULTS

Underrepresentation of older patients in clinical trials makes it difficult to extrapolate findings to older age groups. However, some trials have demonstrated that elderly patients can achieve survival benefits and toxicity comparable to younger patients, although dosage modifications may be required.

CONCLUSIONS

Currently, benefits with pharmacological therapy are suggested but not proven in the elderly population. Although concurrent illnesses and disabilities can complicate treatment decision making, chronological age alone should not disqualify these patients with mCRC from receiving optimal treatment similar to that offered to their younger cohorts.

Untangling the complexities of depression diagnosis in older cancer patients

This review article discusses the complexities of diagnosing depression in older, geriatric cancer patients. There has been little research conducted with this population on the assessment, recognition, and treatment of depression, and thus increased attention is required to improve care for these individuals. Depressive symptoms often manifest themselves differently in both cancer patients and older patients, and therefore a modified and adapted way of assessment must be employed when thinking about diagnosing and treating these patients.

A dilemma in geriatric oncology: malignant bowel obstruction in an 81-year-old man

An 81-year-old male presenting with bowel obstruction was found upon examination to have bilobar liver metastases. In light of the patient's advanced age, bowel resection was foregone in favor of stent deployment, which led to rapid resolution of symptoms. The multidisciplinary team assembled to coordinate further care advised the use of chemotherapy with irinotecan, oxaliplatin, and 5-FU, which was well tolerated and led to an objective response. The special considerations relevant to the patient's advanced age, including the choice of stent deployment rather than resection and the decision to employ 5-FU-based chemotherapy in spite of limited trial data with this approach in patients of advanced age, are explained in detail.

Health-related quality of life and distress in cancer patients: results from a large randomised study

To compare the effectiveness of individual support, group rehabilitation and a combination of the two in improving health-related quality of life (HRQOL) and psychological well-being in cancer patients during 24 months after diagnosis, as compared with standard care (SC). Furthermore, to compare the study sample and a random sample of the Swedish population with regard to HRQOL. A total of 481 consecutive patients, newly diagnosed with cancer, were randomly assigned to one of the four alternatives. Data on HRQOL and psychological well-being were collected at baseline and after 3, 6, 12 and 24 months. The interventions did not improve HRQOL or psychological well-being, as compared with SC. At 3 months, the study sample reported an HRQOL comparable with the normal population. Many cancer patients are able to manage their cancer-related concerns with the support available from SC. However, it is reasonable to assume that the findings suffer from a lack of data from especially vulnerable patients and a possible Hawthorne effect. It cannot be concluded that cancer patients have no need for additional psychosocial interventions. Future projects should include screening and target interventions for those at risk for significant and prolonged psychological distress.

Gastrointestinal stromal tumour in the elderly

AIM

To analyze the outcome of elderly patients compared with the younger age group patients who were diagnosed with gastrointestinal stromal tumours (GIST) at our institution.

METHODS

Patients diagnosed with GISTs were analyzed according to two age groups, those who were at least age 65 and less than age 65.

RESULTS

A total of 49 patients were reviewed. Median age at diagnosis was 59. 18 patients (36.7%) were of age at least 65 or above. Of these 11 patients presented with localized disease. Five patients subsequently developed recurrence with metastatic disease. The median recurrence free survival was 18.5 months. This was not significantly different compared to the younger age group patient (P=0.598). On univariate analysis, the presence of co-morbidities was found to be significantly associated with decrease recurrence-free survival (P=0.046). 13 patients (72.2.%) of the elderly age group had metastatic disease. 8 of these patients had metastasis at diagnosis and 5 developed metastasis at recurrence. The median progression-free survival for these patients was 33 months and there was no significant difference compared to the younger age group patient (P=0.887). On univariate analysis, low albumin was associated with low progression survival (P=0.047). The median overall survival for the elderly patients was 37.6 months. There was no significant difference compared to the younger age group patient (P=0.119). Presence of co-morbidity was associated with lower overall survival in the elderly age group in the multivariate analysis (P=0.037).

CONCLUSION

The elderly with GIST can achieve a similar outcome as younger patients. Presence of co-morbidity was found to affect the survival of elderly patients with GIST.

Does age really matter? Recall of information presented to newly referred patients with cancer

PURPOSE

To examine age- and age-related differences in recall of information provided during oncology consultations.

PATIENTS AND METHODS

Two hundred sixty patients with cancer diagnosed with heterogeneous cancers, seeing a medical or radiation oncologist for the first time, participated in the study. Patients completed questionnaires assessing information needs and anxiety. Recall of information provided was measured using a structured telephone interview in which patients were prompted to remember details physicians gave about diagnosis, prognosis, and treatment. Recall was checked against the actual communication in audio-recordings of the consultations.

RESULTS

Recall decreased significantly with age, but only when total amount of information presented was taken into account. This indicates that if more information is discussed, older patients have more trouble remembering the information than younger ones. In addition, recall was selectively influenced by prognosis. First, patients with a poorer prognosis recalled less. Next, the more information was provided about prognosis, the less information patients recalled, regardless of their actual prognosis.

CONCLUSION

Recall is not simply a function of patient age. Age only predicts recall when controlling for amount of information presented. Both prognosis and information about prognosis are better predictors of recall than age. These results provide important insights into intervention strategies to improve information recall in patients with cancer.

[Is geriatric assessment adapted to radiotherapy?]

Cancer in the elderly represents a major public health topic and its importance will increase in the future because of increased life expectancy and ageing. Cancer prognosis is worse due to late diagnosis, frequent comorbidities and treatment often considered as suboptimal. Reference treatments were primarily validated for younger or selected elderly patients and experimental data collected on most vulnerable are rare. Oncogeriatrics development for 15 years made it possible to consider two fundamental aspects, which are the geriatric evaluation, from the most simple to the complete one, and the development of specific trials. In addition, a strong institutional policy allowed promotion, on the French national territory, of regional experiments thanks to Pilot Units of Oncogeriatrics Coordination (UPCOG). The question of the interest of a geriatric evaluation in radiotherapy is related mainly to the difficulties of tolerance and observance of this treatment, but also with its effectiveness and this review explores the main curative, adjuvant and palliative indications as well as research perspectives.

A systematic review of the use and validation of health-related quality of life instruments in older cancer patients

AIM

The aim of this paper is to systematically review the use and validation of HRQOL instruments in older cancer patients.

METHOD

A systematic review of 5 databases and 3 research registers identified studies reporting the use and validation of HRQOL instruments in cancer patients aged over 65 years from 1995 to mid 2007.

RESULTS

Thirty-one studies reported the use of HRQOL measures in older people, using a range of generic and disease-specific instruments. Little work was reported in patients aged over 80 years. All studies exhibited methodological limitations. Fourteen studies were identified with variable evidence on the psychometric properties and clinical usefulness of identified instruments.

CONCLUSION

Our review identified that the development, validation and use of HRQOL instruments often ignore the specific needs of older people. This review highlights the need for a HRQOL instrument specifically designed to capture the issues and concerns most relevant to older cancer patients.
